Segfault in Ruby VM
ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-darwin18]
Ruby is segfaulting randomly for me on MacOS 10.14 (18A391).
I don't have a script to reproduce the error as it seems to pop up randomly. But I was able to grab the stack trace (attached). It appears to be related to GC.
